“…The greater diversity of dolichopodids in the habitats of vegetable cultivation and fallow, when compared to agroforestry and native vegetation, present an inverse gradient with greater diversity in more disturbed habitats with predominance of herbaceous vegetation, contrary to the general patterns of community studies with other taxa. Generally, a reduction of biodiversity occurs due to the modification of natural habitats and intensification of land use (Pimm & Raven 2000;Flynn et al 2010;Pacheco et al 2013;Uchida & Ushimaru 2014;Lu et al 2016). This unexpected pattern may be partially explained by the organic management adopted on all sampled farms.…”

Adults of the fly family Dolichopodidae (Diptera) are general predators on small soft-bodied invertebrates, and often are abundant in agroecosystems. However, information about their diversity and spatial distribution in agricultural landscapes are scarce. Using structured sampling, we identified the species of Dolichopodidae associated with organic vegetable crops, fallow, agroforestry, and native vegetation in the Federal District of Brazil, and evaluate their richness and abundance. We collected 70 species Dolichopodidae distributed in 17 genera and 9 subfamilies. Of these, some 80% of the specimens belong to the following 5 taxa: Chrysotus spectabilis (Loew), Thrypticus violaceous Van Duzee, Condylostylus depressus (Aldrich), Condylostylus "caudatus group" females, and Condylostylus erectus Becker (all Diptera: Dolichopodidae). Habitats with vegetable crops harbored a higher abundance and number of species (diversity α), with a gradual reduction towards more forested environments of native vegetation. This is an inverse gradient with the general patterns of community studies with other taxa. We also verified the importance of less disturbed habitats over time in the agricultural landscape, such as agroforestry and native vegetation, as complementary habitats for the maintenance and conservation of dolichopodid species in particular, a scenario to be tested for other insect groups.

Biodiversity responses to land‐use and restoration in a global biodiversity hotspot: Ant communities in Brazilian Cerrado

2018

Given that land-use change is the main cause of global biodiversity decline, there is widespread interest in adopting land-use practices that maintain high levels of biodiversity, and in restoring degraded land that previously had high biodiversity value. In this study, we use ant taxonomic and functional diversity to examine the effects of different land uses (agriculture, pastoralism, silviculture and conservation) and restoration practices on Cerrado (Brazilian savanna) biodiversity. We also examine the extent to which ant diversity and composition can be explained by vegetation attributes that apply across the full land management spectrum. We surveyed vegetation attributes and ant communities in five replicate plots of each of 13 land-use and restoration treatments, including two types of native vegetation as reference sites: cerrado sensu stricto and cerradão. Several land-use and restoration treatments had comparable plot richness to that of the native reference habitats. Ant species and functional composition varied systematically among land-use treatments following a gradient from open habitats such as agricultural fields to forested sites. Tree basal area and grass cover were the strongest predictors of ant species richness. Losses in ant diversity were higher in land-use systems that transform vegetation structure. Among productive systems, therefore, uncleared pastures and old pine plantations had similar species composition to that occurring in cerrado sensu stricto. Restoration techniques currently applied to sites that were previously Cerrado have focused on returning tree cover, and have failed to restore ant communities typical of savanna. To improve restoration outcomes for Cerrado biodiversity, greater attention needs to be paid to the re-establishment and maintenance of the grass layer, which requires frequent fire. At the broader scale, conservation planning in agricultural landscapes, should recognize the value of landuse mosaics and the risks of homogenization.

“…Despite the debate, many studies illustrate the ecological benefits of reforestation. Reforestation not only increases forest cover, but also provides a better shelter for understory fauna; research has demonstrated higher species richness and abundance of ants, beetles, birds, and small mammals in reforested areas [ 174 , 175 , 176 , 177 , 178 , 179 , 180 , 181 ]. Similar studies in the megacity of Beijing also illustrate that the diversity birds and beetles in reforested areas is higher [ 182 , 183 , 184 ].…”

About 10% of the Earth’s butterfly species inhabit the highly diverse ecosystems of China. Important for the ecological, economic, and cultural services they provide, many butterfly species experience threats from land use shifts and climate change. China has recently adopted policies to protect the nation’s biodiversity resources. This essay examines the current management of butterflies in China and suggests various easily implementable actions that could improve these conservation efforts. Our recommendations are based on the observations of a transdisciplinary group of entomologists and environmental policy specialists. Our analysis draws on other successful examples around the world that China may wish to consider. China needs to modify its scientific methodologies behind butterfly conservation management: revising the criteria for listing protected species, focusing on umbrella species for broader protection, identifying high priority areas and refugia for conservation, among others. Rural and urban land uses that provide heterogeneous habitats, as well as butterfly host and nectar plants, must be promoted. Butterfly ranching and farming may also provide opportunities for sustainable community development. Many possibilities exist for incorporating observations of citizen scientists into butterfly data collection at broad spatial and temporal scales. Our recommendations further the ten Priority Areas of China’s National Biodiversity Conservation Strategy and Action Plan (2011–2030).
